Project

Aquatic gametes as model for fundamental cell motility studies (LD14119)

The task of this project is to evaluate parameters of sperm flagellar motility of fish or other aquatic organisms and relation of these parameters to resulting speed of sperm movement, and then to develop the modelisation o...
